Mercy the Living Saint

It's kind of hilarious how many "evil" alts they gave the purest healer in the game. I even count the Sugerplum Fairy one among them because I understand what the Sidhe were actually like.

...What? The Imperium are only "good guys" by way of everyone else except possibly the Tau being even worse, and even in-universe documents are willing to admit it (in the case of the Tau bits, mostly because they're willing to help with far fewer strings attached than the Eldar)
